Astronomers have uncovered a massive black hole-powered jet stretching 200,000 light-years — twice the length of the Milky Way. This jet, originating from the quasar J1601+3102, existed when the universe was only 1.2 billion years old. Despite the immense size of its jet, the supermassive black hole at the heart of this quasar is not among the most massive, wiht a mass of 450 million times that of the Sun.
The quasar was discovered in 2022 by a network of radio antennae in the Netherlands that are part of the Low Frequency Array (LOFAR). That revelation, also led by Gloudemans, had revealed that this quasar completely outshines its host galaxy — so much so that it stood out as the brightest among nearly two dozen of its counterparts surveyed by LOFAR.
The newly discovered jet blasts from both sides of an actively feeding black hole — a quasar named J1601+3102, which has 450 million times the mass of the Sun and resides at the heart of a galaxy approximately 10 billion to 13 billion light-years from Earth.
Astronomers Discover Largest Jet from the Early Universe
In a groundbreaking discovery, astronomers have identified what is believed to be the largest jet ever observed in the early universe. This remarkable finding was published in The Astrophysical Journal Letters on February 6, and it has significant implications for our understanding of black holes and their role in cosmic phenomena.
The jet, emanating from a quasar, was frist observed using the Low-Frequency Array (LOFAR), a network of radio telescopes spanning europe. The initial observations were conducted using 14 of LOFAR’s 51 antennae, which provided a detailed image of the black hole’s jet. Though,to confirm the size and extent of the jet,researchers led by Gloudemans conducted follow-up observations utilizing all of LOFAR’s antennae. This effort effectively created a continent-sized radio telescope, enhancing the resolution by 20-fold compared to previous observations.
“We were amazed, but also skeptical, so we made sure to assemble all the evidence before publishing this work,” Gloudemans told Live Science.
The resulting image revealed a northern lobe of the jet located 29,358 light-years from the quasar, as well as a southern blob that appeared to span a whopping 186,954 light-years. Further scrutiny confirmed that the southern blob indeed belonged to the quasar, leading gloudemans and her colleagues to interpret it as the counterjet, thus making it the largest jet observed in the early universe.

The Science Behind the Discovery
Quasars are extremely luminous objects powered by supermassive black holes at the centers of distant galaxies.The jets observed in this study are likely the result of material being accelerated to near the speed of light by the black hole’s immense gravitational pull. These jets can extend over vast distances and are crucial for studying the dynamics of black holes and their environments.
Implications for Cosmic Expansion
The discovery of such a large jet in the early universe suggests that black holes may play a significant role in driving the expansion of the universe. This finding aligns with recent studies that propose black holes could be influencing the cosmic microwave background radiation and the large-scale structure of the universe.
Future Research
This discovery opens up new avenues for further research. astronomers will continue to study these jets to better understand the mechanisms behind their formation and the role of black holes in cosmic evolution. Future observations with advanced telescopes, such as the James Webb Space Telescope, may provide even more detailed insights into these enigmatic phenomena.

An extreme Glow
Although not uncommon in the nearby universe, such large jets have remained undetected in the early universe because the radiation left over from the statement process. despite the jet’s extreme properties, data from the Gemini Observatory in Hawaii show the black hole responsible for the stream is relatively lightweight compared with other quasars from the early universe,which typically have billions of times the sun’s mass.This finding suggests the most powerful jets aren’t necessarily created from exceptionally massive black holes, or from black holes that are heavily accreting material close to the theoretical limit, Gloudemans told Live science.
“We were expecting this newly discovered jet to host an extraordinary black hole, but this wasn’t the case,” she said. More of these extended jets need to be discovered in the early universe for astronomers to better understand how common they were, she said, “but this work at least suggests that a black hole does not need to have an remarkable mass to generate such a jet at this epoch.”
The immense energy released by black hole jets can alter the evolution of galaxies through several interconnected mechanisms that regulate the amount of material available for forming stars. Therefore, J1601+3102 will be a valuable cosmic laboratory for studying how jets influence galaxies in the early universe.
Future observations are likely to reveal more extended radio jets in the early universe, according to Gloudemans. “There are definitely more of these extended radio jets out there,” she said.
